Layer Comps forgetting layer states

I just started using layer comps this year. Granted - I'm new to them, but I think I get it. I understand about the position and layer state buttons, but even when I have all of them clicked some of my layers revert to their original state.

This seems to happen even after I clear the layer style. I'll clear them, or make a change, save the comp, save the doc, and close it. Sometimes when I open it it's fine, sometimes it's reverted. This is EXTREMELY frustrating.
